I wanted to find the best way to measure my macros with meat. I'm not doing competitions or anything extreme, however I would like to be as accurate as possible. I will use chicken breast as an example. I snagged a pack or chicken breasts from Publix and the raw macros were as follows:

Total servings: 4
Serving Size: 4oz
Calories: 130
Fat: 3g
Carb: 0g
Protein: 25g

So a 1lb pack of chicken has 100g of protein, 12g of fat, and 520 calories.

Should I conclude that regardless of what the cooked weight is that the protein numbers didn't change? I'm assuming calories may change along with fat after some weight loss during cooking.

What I did this first round was grill the chicken and then weigh it cooked and just used the measurements against the numbers on the pack. I'm thinking my measurements would be off to some degree because of lesser weight. The raw 100g of protein now becomes lets say 75g when cooked, or is it?

I'm sorry to overthink, i'm kind of a perfectionist and this is how my brain works.

The way I look at it: Did you eat it raw, or cooked?

Chicken breast is pumped full of water; the macros change pretty significantly when cooked. Macros change a lot when cooking fattier ground beef as well. That said, shrimp and fish don't change a lot so I don't usually worry about it much and just log raw weight.

Of course. That's my point.

I'm talking about weighing meat in general, not just chicken breast.

you can't just punch in the numbers. you have to understand that cooked meat is about 2/3 the weight of raw. so 4 oz of cooked meat is about 6 oz of raw. exploiting that across a week it can run up to lot of calories. Makes a difference when trying to get down to a low bf%

OP best way I have found is to either split everything up and weigh raw and cook separate or you can just assume cooked is 2/3 the weight of raw. Use the usda raw value in myfitnesspal.

measure it raw and use those numbers, its the easiest way to do it....don't get lost in the weeds and try to over complicate things.

Question. Would the macros even change that much cooked or is it just the water that makes the weight go down? I'm sure some fat comes off.

The macros don't change per ounce but your weight is different. Pretty much all nutritional values are done using raw meat so it's most accurate. I mean honestly it doesn't matter as long as you are consistent.

Here is a good article on it LINK
